- An unstable particle with a mass equal to 3.34 ✕ 10−27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.981c and −0.861c, respectively. Find the masses of the fragments. (Hint: Conserve both mass–energy and momentum.) m(0.981c) = kg m(-0.861c) = kg - An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 2.30 ✕ 10−28 kg and that...

Two protons (rest mass M = 1.67 * 10^-27 kg) move at same speed in opposite directions. After bumping into each other the protons remain, but as a consequence of the bump a new particle is created, which has a rest mass m = 1.75 * 10^-28 kg. a) Calculate the protons' speed at the beginning by assuming that all particles are in rest after the bump. Give your answer in the unit light speed c. b) Calculate the proton's...

Use Conservation of Mass-Energy to determine how much kinetic energy is released when Radium-224 decays into Radon-220 and Helium-4 (an alpha particle). The relevant masses are mRa = 224.020186u, mRn = 220.011368u, and mHe = 4.002603u. Kinetic energy released: A Uranium-236 nucleus that is initially at rest has a mass of 2.9e-25 kg and is initially at rest. When it decays, it creates two fragments that fly off in opposite directions. Fragment #1 moves to the left at a velocity...
